The Resolve instrument aboard XRISM (X-ray Imaging and Spectroscopy Mission) captured data from the center of galaxy NGC 4151, where a supermassive black hole is slowly consuming material from the surrounding accretion disk. The resulting spectrum reveals the presence of iron in the peak around 6.5 keV and the dips around 7 keV, light thousands of times more energetic that what our eyes can see. Background: An image of NGC 4151 constructed from a combination of X-ray, optical, and radio light. Spectrum: JAXA/NASA/XRISM Resolve. Background: X-rays, NASA/CXC/CfA/J.Wang et al.; optical, Isaac Newton Group of Telescopes, La Palma/Jacobus Kapteyn Telescope; radio, NSF/NRAO/VLA
After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the ...
Scientists studied NGC 7319, part of the visual grouping of galaxies called Stephan’s Quintet, using the Medium-Resolution Spectrometer (MRS) in the Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope. The galaxy contains a supermassive black hole that is actively accreting material. The spectrometer features integral field units (IFUs) – each containing a camera and spectrograph. IFUs provided the Webb team with a collection of images of the galactic core’s spectral features, shown here. Blue-colored regions indicate movement toward the viewer and orange-colored regions represent movement away from the viewer. Powerful radiation and winds from the black hole ionize hot spots of super-heated gas, creating the argon and neon lines...Read More
